Mitigating the risk of secondary fires at MSW bale storage sites
http://www.inderscience.com/link.php?id=137348
The article discusses the suitability of several existing empirical models for determining the safe separation distances (SSDs) for waste fuels. Contour plots of SSDs are generated based on isotropic thermal radiation model for safely storing municipal solid waste (MSW) bales under different storage settings and the plots can be employed for routine hazard assessment purposes. Further, experimental design technique was employed, and orthogonal test matrices were generated to conduct the experiments for studying the combustion dynamics of the primary fire under the influence of storage settings of surrounding fuel units. The main and interaction effects of various storage parameters (e.g., height of adjacent fuel sources, clearance between fuel sources and array size) on the response variables (flame height and burn out time) were studied. A list of appropriate measures for minimising the risk of secondary fires at MSW bale storage sites is provided.

Theoretical and experimental analysis of the passenger's reading comfort to luminous environment in Chinese high-speed trains
http://www.inderscience.com/link.php?id=137349
This paper is aimed at finding the nature of passengers' reading comfort in Chinese high-speed trains to the luminous environment. First, based on the ideology of photon mapping, the theoretical analysis is conducted to reveal the mechanism of the passengers' reading comfort qualitatively. Then, based on the experimental data gained from the comprehensive comfort test-rig, the mechanism of the reading comfort is developed quantitatively based on fuzzy algorithm. Results show that the best illumination for the reading passengers ranges from 175 Lux to 450 Lux and the best range of the colour temperature should be approximately natural. Moreover, the higher the illumination is, the more likely that the passengers will feel comfortable in higher degree of colour temperature. These conclusions can be applied in guiding the design of the comfortable luminous environment of Chinese high-speed trains.

Landscape planning and design of an ecological characteristic town and its impact on tourism
http://www.inderscience.com/link.php?id=137350
In order to improve the tourism economy of rural areas, the local landscape needs to be planned to realise sustainable development. This paper analysed the landscape planning of an ecological characteristic town by taking Wenglangxi Village, Longchuantang Yao Nationality Town, Hongjiang City, Hunan Province, as a case. The landscape planning scheme of the ecological characteristic town for Wenglangxi Village was given after introducing the local profile and planning principles, and the changes in tourism in Wenglangxi Village in three years before and after the landscape planning were measured using the coupling coordination model. The results showed that the coupling coordination between tourism and ecology in Wenglangxi Village decreased year by year before the landscape planning and increased year by year after the landscape planning.

Evolutionary design framework and assessment of the sustainable manufacturing systems
http://www.inderscience.com/link.php?id=137358
The need for sustainability in modern manufacturing systems is influenced by environmental-driven objectives including lower emissions, minimal utilisation of natural resources, reduced energy usage, etc. In this work, for developing green manufacturing systems, optimal improvement plan is implemented using recycling tool without affecting productivity. Using survey data based on recycled content, this paper empirically evaluates various environmental metrics affecting water management, climate change, air quality and greenhouse gas impact. In addition, we provide an estimate of net energy consumption and global average carbon emissions for different types of materials employed in manufacturing industry. The iterative execution of evolutionary genetic algorithm is implemented for minimising the greenhouse effect by considering the application of distinct selection, mutation and crossover operations. Moreover, simulation results demonstrate that the proposed design model outperforms the previous works in terms of reduced emissions by up to 86%, energy conservation by huge proportion of 247.2 and 72.86% lesser carbon footprint.

Confined spaces at construction sites
http://www.inderscience.com/link.php?id=137357
The objective of this article is to analyse the activities in the confined spaces of several industries to verify the state-of-the-art and identify the factors that contribute to the occurrence of accidents, as well as the tools, methods and technologies used in the management and control of the risks. The research used the systematic literature review (SLR). Of the 21 accepted papers, eight explored risk management and control in confined spaces (33.3%). The use of technologies appeared in six articles (28.6%) and the monitoring of environmental agents in five articles (23.8%). The main contributing factors for accidents were failures in the management process, lack of safe procedures, unsafe operations, financial restriction and training deficiencies. The studies showed the development of risk management and monitoring tools, and the use of technology as a way to improve worker safety.
